CircuitWorks Thermal Paste

CircuitWorks® Thermal Paste facilitates heat transfer away from electrical/electronic components. This heavy consistency material is thickened with a heat conductive filler to maintain a positive heat sink seal in electrical/electronic equipment.

Heat Sink Grease (CT40-5)

  • Silicone-base
  • Thermally stable from -52ºF (-46ºC) to 603º F (317ºC)
  • Meets MIL-DTL-47113D Type I

Silicone Free Thermal Paste (CW7270)

  • Silicone free compound avoids silicone migration
  • Thermally stable from -99.4°F(-73°C) to 392°F (200°C).  
  • Exceeds MIL-C-47113 for thermal conductivity

Boron Nitride Thermal Paste (CW7250, CW7250KG)

  • Provides maximum thermal conductivity with superior dielectric properties
  • Silicone free compound will not harden or dry out
  • Thermally stable from -99ºF (-73ºC) to 392ºF (200ºC)
  • Exceeds MIL-C-47113 for Thermal Conductivity

  • Facilitates heat transfer between circuit components and heat sinks
  • Excellent thermal and dielectric properties
  • Will not dry out, harden, or melt
  • Noncorrosive and nonflammable
